Product Details

Specifications

1.Calibrates a transmitter using the split-screen
2.Manual stepping and automatic stepping and ramping

Features and Benefits

A split-screen display. The upper display allows you to measure volts, current (with loop power), resistance and continuity test. The lower display allows you to measure and source volts, current, resistance temperature detectors (RTD), thermocouples (TC), frequency, and ohms.
Calibrates a transmitter using the split-screen.
The measure of thermocouple provides automatic reference junction.
Automatic and manual cold end temperature compensation for TC.
Manual stepping and automatic stepping and ramping.
Super-strong protection:The waterproof grade is IP67. Automatic protection against the signal terminals connect to the 220V.
